Plainly, both the cameras enjoy different megapixel count and different sensor sizes. The FE-5020 using its smaller sensor will make shooting shallow depth of field harder and the Pentax 645Z will show greater detail with its extra 39MP. Higher resolution will enable you to crop pictures far more aggressively. The more aged FE-5020 will be behind with regard to sensor technology.
